Majority of studies evaluating functional capacity of adults with congenital heart defects show reduced physical tolerability due to the cardiac defect per se. As well as congenital heart defects vary the results of cardiopulmonary testing (CPT) can also be different. Not only CPT is useful for the preoperative prognosis of adverse events but also it is helpful in the long-term prognosis and supervision of physical trainings and their efficiency. Hereby we describe some of the most significant CPT parameters valid for clinical practice and prognosis. Following pointers are highlighted – optimal cardiorespiratory point, ventilatory anaerobic threshold, indicator of oxygen consumption efficiency etc. Some of these parameters independently or in combination show the best agreement with maximal oxygen consumption and may be useful for the determination of cardiorespiratory functional capacity in this group of patients.
